LONDON: Disgraced Australian duo Steve Smith and David Warner have been told they have it all to prove as they return to top-level cricket. The pair finished their year-long ban for ball-tampering this week and will play in the big-bucks Indian Premier League, which gets under way tomorrow. The timing of the cash-rich Twenty20 circus is awkward, however, wrapping up less than three weeks before the start of the World Cup in England and Wales. It has long been assumed that both would walk back into the side, but former Australia captain Ricky Ponting has warned them they need to get runs in India if they are to get on the place to the 50-over global showpiece. “Those guys have not played any high level cricket for a long time,” Ponting told the Times of India newspaper. “They still have to prove they are the best players. “If they don’t have a good IPL, then there will be a few more question marks regarding their names,” said Ponting, who is head coach IPL side Delhi Capitals. The ban only included international and state-level games so both Smith and Warner were able to play in the Bangladesh Premier League but both soon bowed out because of elbow injuries, and now they are keen to get noticed again by Australia’s selectors. The lucrative league kicks off with three-time winners and defending champions Chennai Super Kings, captained by Mahendra Singh Dhoni, hosting Virat Kohli’s Royal Challengers Bangalore on Saturday. Warner will play for Sunrisers Hyderabad along with Afghan spin sensation Rashid Khan and New Zealand’s Kane Williamson against Kolkata Knight Riders on Sunday. Smith is likely to be in action for Rajasthan Royals, along with England’s Ben Stokes and Jos Buttler, on Monday against Delhi Capitals.
